A clear science explanation breaks down how lightning forms and why it branches through the air instead of traveling in a straight line to the ground. Real-life Haribo! Ultra-rare two-headed snake ...

At 10:03 a.m. Sunday morning, the sun was directly over the Tropic of Capricorn at 23.5° south latitude, marking the December solstice, and the beginning of winter in the Northern Hemisphere. Other ...

Shortest path algorithms sit at the heart of modern graph theory and many of the systems that move people, data, and goods around the world. After nearly seventy years of relying on the same classic ...

YORKTOWN HEIGHTS, N.Y., Nov. 12, 2025 /PRNewswire/ -- At the annual Quantum Developer Conference, IBM (NYSE: IBM) today unveiled fundamental progress on its path to delivering both quantum advantage ...

When Edsger W. Dijkstra published his algorithm in 1959, computer networks were barely a thing. The algorithm in question found the shortest path between any two nodes on a graph, with a variant ...

The original version of this story appeared in Quanta Magazine. If you want to solve a tricky problem, it often helps to get organized. You might, for example, break the problem into pieces and tackle ...

There is a new sorting algorithm a deterministic O(m log2/3 n)-time algorithm for single-source shortest paths (SSSP) on directed graphs with real non-negative edge weights in the comparison-addition ...

If you want to solve a tricky problem, it often helps to get organized. You might, for example, break the problem into pieces and tackle the easiest pieces first. But this kind of sorting has a cost.

Abstract: This paper investigates the shortest path planning of unmanned surface vehicles (USV) in complicated marine environments. A novel path planning method called “sunlight algorithm” is first ...
